as you can see in this small video(30s), my snippet isn't working. how to fix it?

i add a plugin call nvim-tree and i config them like this:

local status, nvim_tree = pcall(require, 'nvim-tree');

if (not status) then return end


nvim_tree.setup({
  sort_by = "case_sensitive",
  view = {
    adaptive_size = true,
    mappings = {
      list = {
        { key = "u", action = "dir_up" },
      }
    }
  },
  renderer = {
    group_empty = true,
  },
  filters = {
    dotfiles = true,
  },
  diagnostics = {
    enable = true,
    show_on_dirs = false,
    debounce_delay = 50,
    icons = {
      hint = "´ü¬",
      info = "´üÜ",
      warning = "´ü▒",
      error = "´üù",
    },
  }
})
